摘要
采用控释氮肥在玉米上进行肥效试验研究。结果表明:施用氮肥处理产量比CK增产6.6%-14.1%,控释氮肥在玉米上具有明显增产效应;控释氮肥有促进玉米生长发育的作用,施用控释尿素较常规施氮肥处理氮肥利用率提高了13.44%;降低30%的氮肥用量,较常规施氮肥处理氮肥利用率提高14%;控释尿素处理对玉米蛋白质含量、氨基酸含量和维生素E含量无明显的影响。
The effects of controlled-release nitrogen fertilizers(CRNF)on maize were studied.The results showed that:the maize yield of fertilization treats increased by 6.6%~14.1% than CK,and CRNF showed yield increasing effect obviously;CRNF could promote the maize growth,and in comparison with N2 the nitrogen utilization efficiency of N3 enhance 13.44%,one of N4,with the 70% N2 content of nitrogen,enhance 14%;the content of Pro,amino-acid and vitamin E was not significantly increased with the application of CRNF.
